30305 – A micro electro-mechanical system (MEMS) device that incorporates its own UV radiation source and thin film technology to detect hydrogen at low concentrations and at room temperature
Hydrogen gas is currently used for a variety of industrial, commercial and scientific purposes. While extremely useful, it is also highly combustible, even at concentrations as low as 4% by volume. The... Read More

31571 – The invention provides the means, materials and methods for creating an in-line passive micro-mixer to be combined with a micro-fluidic sensor. This device makes use of variations in side-wall shapes to alter the flow rates of miscible liquids. These side-wall shapes are comprised of polymer resins cast from a silicon wafer mold.
The field of micro-fluidics is growing rapidly, with... Read More

30949 – A nanoceria based regenerative radical sensor for plasma testing, food quality control, or drug development
UCF researchers have developed an electrochemical sensor for the measurement of free radicals, or materials that generate free radicals, in solution. Ideal for biomedical, pharmaceutical, or sensor companies, this sensor has a long lifetime with the option of multiple uses. With an... Read More

30257 – UCF researchers have designed a reliable, easy to manufacture, and inexpensive microfluidic portable water sensor with disposable cartridges—capable of determining microbe growth, chlorine content, purity, or temperature.
Microfluidics, or “lab-on-a-chip” technology, is experiencing explosive growth in the fields of chemistry, biology, electronics, and computers. These small devices work... Read More
